First, we have the Hot Slippers (pictured above). They are available in brown or grey and get the power they need to keep your feet warm through the USB port of your computer (Windows or Mac OS will work). Price: $23 per pair.

Then there are the Hot Room Shoes. I am not really sure what the difference to the Hot Slippers is function-wise, as these shoes are supposed to keep your feet warm via USB power, too. Price: $23 (available in M or L).

Thanko already sells both versions on their Japanese website. As the company closed their English store recently, you’ll need to contact import specialists such as the Japan Trend Shop or Geek Stuff 4 U to get a pair.
